Title:
THZ SENSOR AND THZ METHOD FOR MEASURING AN OBJECT TO BE MEASURED
Document Type and Number:
WIPO Patent Application WO/2022/117156
Kind Code:
A3
Abstract:
The invention relates to a THz sensor (2) for measuring an object to be measured (6), in particular a pipe, the THz sensor (2) having: a THz transceiver (10) for emitting and receiving THz radiation; a lens (14) for bundling the THz radiation emitted by the THz transceiver (10) and emitting a THz transmission beam (8) along the optical axis (A) and for receiving a THz reflection beam (15); and a support device (11) on which the lens (14) and/or the THz transceiver (10) is accommodated or fastened. According to the invention, a THz radiation-influencing compensation formation for modifying and/or reducing incident THz radiation is provided in a compensation region between the lens and the support device (11).
